← Logic & PuzzlesA database query optimizes relation joins using dynamic programming; what happens to memory use as the number of joined tables increases?
A)Decreases due to early optimization
B)Increases due to storing intermediate results✓
C)Remains constant regardless of relations
D)Fluctuates randomly, no predictable trend
💡 Explanation
Memory usage increases because dynamic programming stores intermediate results of subproblems to avoid recomputation; therefore, as the number of tables and joins increases, more intermediate tables are stored, increasing memory consumption, rather than remaining constant or decreasing.
